MY AIR CONDITIONER WILL WORK GOOD FOR ABOUT 10-12 HOURS AND THE NEXT DAY I WILL AND CHECK THE RV AND THE CIRCUIT BREAKER WILL HAVE POPPED WHAT WOULD CAUSE THIS TO HAPPEN. IT COOLS GREAT.
THANK YOU
Re: MY AIR CONDITIONER WILL WORK GOOD FOR ABOUT 10-12...
Most likely the condenser is very dirty and the compressor pull more amps than is suppose to and when this happens the breaker tripps.start by cleaning the condenser with a design conderser cleaner.

The best guess is that you have a bad thermostat. When the compressor shuts off it has to stay off for a long enough period of time for the low pressure high pressure to equalize. If it turns the compressor off and back on immediately it can't start against the heavy load created by these unequal pressures. If it will start every time after sitting for 10 minutes the thermostat is making it short cycle.
Check your voltage to the unit. Be sure to use a big cord when hooking up your camper. Does the unit have a wall mounted thermostat? Does the blower run? When was it cleaned last?
Two things that you could check: 1) If you have access to an ampmeter, determine if the unit is drawing over over 14 or 15 amps, 2) replace the suspect circuit breaker in case it is beginning to go bad. Breakers only trip for overcurrent conditions or failure of the breaker itself. If it is pulling close to 15 amps, then it could heat up over time and trip.
If the unit has been serviced recently and they added refrigerant to it, then it's possible that they overcharged it causing it to have high head pressure which will increase the amp draw enough on a hot day to trip the breaker.If the unit hasn't been serviced, you might won't to check the condenser coil to see if it's dirty, if its not dirty then check the voltage to the unit, if you're in an RV park when everybody there is running there ACs the voltage may be to low for your unit to run. What fan speed are you running on you may need to run it on high speed during the day.
